OIL-STOVE ATTACHMENT.

Application filed October 24, 1917.

To all whom it may concern:

lie it known that I, JA MES T. KELLEY, a citizen of the United States,and a resident of West Rush, in the county of Monroe and State of NewYork, have invented a new and Improved Oil-Stove Attachment, of whichthe following is a full, clear, and exact description.

My invention relates more particularly to oil cook stoves. In the use ofoil. cook stoves the burners develop a high degree of heat but much ofit radiated laterally by the chimney of the burner and also, the heat isnot carried by the chin'iney close to the burner grid which is spaced amaterial distance above the to flange with which the chimneys are usualy provided.

The prime object of my invention is to provide a jacket ofnon-heat-conducting material to be applied to the chimney of an oilstove and spaced therefrom, whereby to prevent any material radiation ofthe heat from the chimney into the room, and arranged to be supported onthe top of the chimney in a manner to dispose the top of the jacketabove the chimney to deliver the heat sufliciently close to the grid.

A further object of the invention is to provide in connection with thejacket as characterized a heat deflector that will permit a properproportion of the heat to pass directly through the grid at the centerwhile deflecting a portion of the heat laterally in all directions, sothat the heat will not be concentrated at the center of the cookingvessel as is done at present.

Other objects of the invention and the advantages of my attachment willappear as the description proceeds.

Reference is to be had to the accompanying drawings forming a part ofthis specification in which similar reference characters indicatecorresponding parts in all the views.

Fig. 2 is an enlarged transverse section of the attachment showing thesame applied to a stove chimney, a portion of which is broken away, theView showing a fragment of the stove plate with one of the grids thereofin transverse vertical section:

Specification of Letters Patent.

Serial No. 198,246.

In the drawings the letter A indicates an oil cook stove of knownconstruction; Ii, a chimney of one of the burners; G, the oilreservoirs; and I), the stove plate havin g the grids E on which thecooking vessels are placed.

In carrying out my invention a cylindrical jacket 10 is provided ofnon-conducting material, the illustrated form comprising two layers, theouter layer in practice being made of paper While the inner layer is ofasbestos, it being understood that the material can be varied. In orderto support the jacket on the top of the chimney B and spaced from thesides of the latter, I provide a hanger which advantageously is in theform of a wire ring 11 adapted to rest on the top flange b of thechimney. The ring affords an open center for the free passage of theproducts of combustion from the chimney to the grid. In the illustratedform the ring 11 is secured to the jacket 10 by radial arms 12 rivetedor otherwise secured at their outer ends to the jacket as at 13. Thering in the form illustrated is composed of a single annular wire or rodwhich is twisted with separate Wires carrying pairs of arms 12. Thenumeral 14 indicates curved plate springs secured at one end to thejacket 10 at the interior and adapted to hear at their inner endsagainst the sides of the chimney B, said rings and the arms 12 servingto properly center the jacket on the chimney. The hanger 11, 12 is sopositioned as to dispose the ring below the top of the jacket 10,whereby the said top will project above the top of the chimney B tocarry the products of combustion from the chimney closer to the grid Ethan is done by the chimney itself.

In order to prevent heat from the chimney being concentrated at thecenter of the cooking vessel on the grid E, I provide a deflector 15 ofinverted cone-shape and provide means to support the same at the centerin line with the center of the grid, the illustrated means consisting ofradial arms 16 extending from the deflector to the upper edge of thejacket 10. The heat deflector 15 is formed with an annular series ofopenings 17 to permit the direct passage of heat toward the center ofthe grid E, while at the under side of the deflector I form thereonwings 18 of such form and at such an angle as to direct a certain ortionof the heat currents laterally past t e outer edge of the delleclmtoward the outer edge of the grid, and hence toward the outside of thecooking vessel. Advantageously, the openings 17 are triangular and thematerial of the deflector is stamped out in a downward direction toproduce both the said openings and the wings 18.

I wish to state in conclusion that although the illustrated exampleconstitutes a practical embodiment of my invention, 1 do not limitmyself strictly to the mechanical details herein illustrated, sincemanifestly the same can be considerably varied without departure fromthe spirit oi" the invention as defined in the appended claims.

Having thus described my invention, I claim as new, and desire to secureby Letters Patent:

1. An attachment for oil cook stoves, including a cylindrical jacketadapted to be removably positioned on the stove chimney to inclose thesame, a hanger at the interior of the chimney, said hanger comprising aring below the top of the acket adapted to Copies of this patent may beobtained for five cents each, by addressing the rest on the chimney atthe top and having radial arms extending from said ring to the jacketand secured to the latter, and curved plate springs secured to thejacket at the interior near the bottom and free at their ends toyieldingly bear against the sides of the chimney.

2. An attachment for oil stoves including a cylindrical jacket adaptedto be reinovably positioned on the stove chimney to inelose the same, ahanger on the jacket below the top thereof to support the jacket on thechimney, a heat deflector in the form of an inverted cone formed withradial openings therein for the direct upward passageof heat, radialwings on the deflector at the openings along one side of each opening,and spaced supporting arms on said deflector and extending therefromoutward to the jacket above said hanger to sustain the deflector on thejacket above and clear of the chimney.
